Patent DE-19628217-A1 (DE)
Inventor: ZENZEN MARKUS
IPC: B60T8/88
Filed: 1996-07-12
Abstract: The present invention makes it possible to recognise a breakdown of the front axle braking circuit without adding a manometric switch to the front axle braking circuit. For this purpose, the disclosed braking system has an electronic computing unit which observes the wheel slip difference between front axle and rear axle when driving on a straight road and which compares the speed differences between left and right front wheel and left and right rear wheel when driving in a curve. If the rear wheels turn more slowly than the front wheels without any brake slip control or if the wheel speed difference at the rear axle is larger than the wheel speed difference at the front axle when driving in a curve, a front axle brake circuit breakdown is signalled, provided further criteria are met. Any electronic brake power distribution which may be in effect at the time is then stopped.
Patent DE-19632282-A1 (DE)
Inventor: HOLZER WALTER PROF DR
IPC: H05B41/392
Filed: 1996-08-09
Abstract: The invention describes a method for the modulation of the light intensity of fluorescent lamps via the supply main by modification of the form and/or the amplitude of the power supply provided. An electronic control element, provided as a component of the logical circuit, temporarily blocks current flow after at least every second zero-crossing of the voltage, dependent upon time and/or voltage. Blocking of the current flow occurs only during the time period in which there is no flow of charging current for the downstream direct-current mains supply circuit. The advantage thus obtained is that the control pulses for the logical circuit do not influence the electric current flowing through the fluorescent lamps.

Patent DE-19638704-A1 (DE)
Title: Folding ladder with wires or bands instead of stringers
Inventor: LUCKEY BERND
IPC: B63B27/14
Filed: 1996-09-21
Abstract: The folding ladder has a number of horizontal transverse rungs (2,4) which are connected together by two wires or bands (6). These wires or bands have carabineer hooks (10) at their top ends and small eyes (8) at the bottom end, to enable the ladder to be hung from an overhead support and to enable several ladder sections to be connected together. The rungs are of inverted U-section (16) with a flat top acting as a tread surface. The sides of the U slope outwards from the tread surface. Clamping rings (30) fix the ends of the rungs to the wires or bands. Alternate rungs have spacers (18) projecting from their ends to keep the rungs form hanging too close to the wall.
Patent DE-19640526-A1 (DE)
Inventor: SCHEERHORN ALFRED DR ING
IPC: H04L9/32
Filed: 1996-10-01
Abstract: A process for transmitting sequences of signals/data from a transmitter to a receiver and for authenticating the sequences of signals/data consists of a precalculation phase and of a communication phase in which the signals are transmitted together with the checking sums. In the precalculation phase, a pseudo-random sequence is first generated by means of a cryptographic algorithm from a time-variable parameter and other initialisation data. Non-overlapping sections (z(1)) of a sequence (z) having each m bits are associated to signals (s(i)), wherein i = 1, 2, ... n, of a signal storage. Further non-overlapping m bit sections (t(i)) of the remaining sequence are selected for coding numbers (1, 2, ... MAX). The transmitter transmits the initialisation information and the time-variable parameters to the receiver and the receiver calculates the pseudo-random sequence (Z) and checks the received authentication token (T). The transmitter accepts the received signals as being authentic when the received authentication tokens match the calculated ones.

Patent DE-19714945-A1 (DE)
Inventor: GAHANG GOO-SOO
IPC: H04N1/401
Filed: 1997-04-10
Abstract: An image forming apparatus is described including a white reference body and an image sensing means for scanning the reference body or a document to produce digital pixel data. The CPU of the apparatus controls the image sensing means to scan the reference body to produce analogue image data, converted to digital pixel data by an ADC. For each pixel, the CPU determines a shading factor by dividing a predetermined maximum brightness value by the digital pixel data. The CPU also controls the image sensing means to scan a document to produce analogue image data, again converted to digital pixel data by the ADC. For each pixel, the CPU determines shading-compensated pixel data by multiplying the digital pixel data by the corresponding shading factors. Finally, a half tone image of the scanned document is produced from the shading-compensated pixel data.

Patent DE-19723054-A1 (DE)
Title: Electromechanical control for tilting door, esp. garage door
Inventor: BUBENDORFF RICHARD
IPC: E05F15/16
Filed: 1997-06-02
Abstract: The up-and-over garage door is hung in the door frame, and counterbalanced by two ballast weights looped over the drive pulleys. The pulleys are each connected to drive shafts which meet in a drive unit (14) over the door.  The electric motor shaft operates the drive shafts via meshing cylinder gears (28,24), with the output gear loosely fitted on the drive shaft.  The output gear drives a gear (19) which is rigidly fitted to the drive shaft, and this gear meshes with the short gear rack (36) fitted to the top edge of the door. The coupling between the output gear and the driven gear is via dog teeth between the ends of the gears and with the axial pressure between the gears provided by an elastic element. This provides a limited torque coupling.
Patent DE-19724278-A1 (DE)
Inventor: CHA MYOUNG-SIK
IPC: H04M1/724
Filed: 1997-06-09
Abstract: A mobile phone is provided with the facility to lock/unlock its keyboard following the input of a locking/unlocking command. In the locked state, the phone stops scanning the keypad 113 and can only revert back to an unlocked state via the use of a release key. This stops the mobile phone from being woken up when a user accidentally depresses one of the keys whilst it is in sleep mode. locking/unlocking of the phone may be executed via the volume slider 115 or may alternatively involve the use of the hash key 116. The telephone may be programmed to automatically enter the locked state following a predetermined interval of inactivity. Saves energy by reducing keypad scanning power and preventing accidental transition from idle to active state.

Title: Ozone disinfection of bromide-containing bath water
Inventor: BACHHOFER BRUNO
IPC: C02F1/78
Filed: 1997-06-11
Abstract: Bath water is disinfected by mixing ozone with water to which bromide has been added such that the excess of ozone remaining (after reaction with predominantly organic contaminants) reacts with the dissolved bromide to reduce the ozone to oxygen and to oxidise the bromide to oxygen-active hypobromite. The novelty is that the thus-treated water is UV irradiated prior to use.

Patent DE-19737818-A1 (DE)
Title: Cooling water circulation circuit for vehicle IC engine
Inventor: AOKI SHINJI
IPC: F02B29/04
Filed: 1997-08-29
Abstract: The coolant circuit of the IC engine has an additional control valve, solenoid operated, to control the temperature of the engine coolant. The engine temperature is varied to match the torque requirements. A thermal storage element (4) stores hot coolant taken from the engine and passes same to the recirculating pump. When the engine is switched off the inlet and outlet of the thermal storage element are closed off to reduce thermal loss to the rest of the coolant circuit through convection. A controller monitors the state of the engine and switches the solenoid valve if the engine is not running. When the engine is switched on again hot coolant is added to the coolant circuit to raise the engine temperature rapidly to the operating level.
